Artificial wax.



I06. COMPOSITIONS,

To all whom it may concern.-

Be it known that I, JULI'US LEWY, a sub- .ject of the King of Prussia, German Emperor,

and a resident'of Biebrich-on-the-Rhine, in

- the Kingdom of Prussia, German Empire, have invented new and useful Improvements in Artificial Wax, of which the following is a fnll, clear, and exact specification.

By my invention a ketone of the acetone series or a mixture of such ketones is added to substances usedin making artificial-wax composition destined, for instance, for the manufacture of candles, wax matches, max flowers, and the like, such as paraifins or mixf u o I tures of pa'raflin-with ceresins or stearin, (a.

, mixture of tearic acid and palmitic acid,)

such as are nsed'fmuaking so-called com-- posite candles, and other mixtures. This addition has the effect of suppressing the more or less great transparency of paraffin and of the mixtures of paraflin with the compounds mentioned above and will give to these substances the white colorof good stearic acid, a fact particularly valuable in the manufac-. ture of composite candles, imitated wax matches, wax flowers, and the like. Furthermore, if these new mixtures are used in the manufacture of candles these candles get an increase of their illuminating power and produce a bigger andwhiter flame than candles without the addition of acetone or itshomologues. Finally, the bad smell that appears when other candles are extinguished is suppressed. The proportion of the ketone or ketones may vary within large limits, and the mixture is made at a temperature suitable to the nature of the materials used.

The acetone or its homologues are mixed with the other substances used while these are in a melted condition. The evaporation of the added ketones is avoided by operating at sufliciently low temperatures or in a closed vessel provided with a reflux-cooler. The melted material must be constantly stirred while adding the ketone or ketones in order to obtain a homogeneous mixture. Good results have been obtained, for instance,'ac-

cording to the following examples. The parts E' xample 2;Fifteen (l5)'parts of acetone Patented August 4, 1905 UNITED STATES PATENT GFFICE.

are added to a melted mixture of seventy (2 parts of paraflin andfiftee'n (l5)'; .par ts stearin; but I can obtain the desired eliect an addition of much less acetone and stem to paraffin, as shown in the following exa p es. I Example 3:. Five (5) parts of acetone 2 added to a melted mixture of five (5) parts stearin and ninety (90) parts of paraihn.

Example 4 Five (5) parts of acetone 2 added toa mixture of (5) parts of ceresin wi ninety (90) parts of paraflin.

. Example 5: Five (5) parts of acetone :1 added toa mixture of five (5) parts of 'ceresi five (5) parts of stearin, and eighty-five (5 parts of parafiin. v

In all these examples instead of acetone 0 of its homolognes, or mixtures thereof, su as the so-called acetone-oils, may be use It must be understood that instead of usi solely paraflin or the mixture of paraflin a stearin, &c. coloring substances and such a ditions may be intermixed which are able lower or to raise the melting-point of the mi ture. 4

I am aware that acetone has been here1 fore proposed as a solvent for parafiin. Su a mixture, however, differs radically fromt new mixture, inasmuch as .in the latter t paraflin is in excess and is therefore not he in solution. V

Having thus described my invention, claim as new and desire to secnre'by Lotte Patent P f 1. Asa new composition of matter, a mi ture containing'a ketone of the acetone seri and an excess of paraflin.

In testimony that Iclaim the foregoing. my invention I have signed my name in pm once of two subscribing .witnes'ses.
